Creating a mesh in a 3-d plot.
显示 更早的评论
Hello matlab community,
Can someone please help me to create a mesh surface where the points are connected and it looks like the picture attached. I have the following code which just connects the points with the line but the surface is not seen. I am not able to figure the meshgrid and how to apply it to fit my requirement. I would be really grateful if somone can help.
opts = detectImportOptions('Data1.xlsx');
opts1 = detectImportOptions('Data2.xlsx');
% Load data
data = readtable('Data1.xlsx', opts);
data1 = readtable('Data2.xlsx', opts1);
x1 = data{:,1};
y1 = data{:,2};
z1 = data{:,3};
x2 = data1{:,1};
y2 = data1{:,2};
z2 = data1{:,3};
figure(1)
plot3(y1,x1,z1, 'x-o','LineWidth',1);
hold on;
plot3(y2,x2,z2, 'x-o','LineWidth',1);
hold off;
legend('$25^{\circ}C$','$150^{\circ}C$',...
'Location','northoutside','Orientation','horizontal')
